When I feel like I’m orgasming in a dream, am I actually having a physical orgasm?

I understand this may be an odd question to ask, but I am very curious to understand what’s going on when I experience this. I am a female in my early twenties. Last night I had a very intense erotic dream, and I literally felt like I was experiencing a few orgasms. I was extremely aroused in the dream and experienced the actual sensation of orgasming. The odd thing is, when I woke up, I wasn’t wet at all. I just felt as if I had been aroused for a long time, like I was engorged. My question is, was I really experiencing an actual orgasm as I was dreaming or was it just in my mind?
